Coach Bruce Arians said Wednesday that Miller (hamstring) won't travel for Friday's preseason game against the Steelers, Greg Auman of The Athletic reports.
The injury isn't supposed to be a long-term one, but Nelson did tweak his hamstring during Monday's practice, and it will hold him out of at least one game. The 2019 sixth-round has made a strong impression so far in camp but will miss out on valuable reps to get up to NFL speed.
